CENTRAL, S.C. (WHNS/CNN) - Authorities arrested three people Monday in connection with the death of a Clemson University student.

Steven Grich, 23, died Saturday after police say suspects broke into his off-campus home and shot him.

The Chimney Ridge subdivision isn't far from the Clemson University campus. Most of its residents are college students.

On the outside, it looks like a safe, gated community.

The news that a student was shot to death in a home invasion hits too close for many students.

"It's scary because it's so close to campus, and I feel like being, going to Clemson, it's such a safe campus. Our sorority sisters live in Chimney so it's, I mean it could have been any one of them," said a student named Jocelyn.

University emails were sent out to some students, one serving as an obituary for the victim, Steven Grich, an electrical engineering student at the school from Fort Mill, South Carolina.

In it, Dean of Students Joy Smith says "We are so sad about this sudden loss of one of our students. The death of a young person is always a tragedy, but it is especially so at this time of year."

The other served as a warning to students.

Campus police ask students to lock their doors and report suspicious activity.

Students are hoping the school will keep them informed.

Three men were arrested and charged with the robbery and murder.

Warrants have been issued for a fourth suspect, an 18-year-old.

Investigators do not believe Grich knew his attackers and believe the robbery had to do with drugs.
